He was nice, was very quick and direct. He even put the screen back on my window, even though I had knocked it out earlier. Well done.


Flange broken




Review of Mike Diamond Plumbing, Inc.

Having my floor replaced and the flange to my toilet was broken. Roots were under the flange and broke it. Bryan and Matt came out and looked at it, they were able to give me a senior discount and when the manager came out e discounted it even more. The job was completed working the expected time frame and the flooring can continue as scheduled. I Couldn’t have asked for a finer group of guys to come do the job.
